Acoustic Revive
RHR-21
Acoustic Resolution Exciter

Revolution in room tuning!

Dramatically improve the resolution and phase characteristics of your listening room.

Although the RHR-1 is small, it has a standing wave elimination effect that far exceeds the effect of large room tuning elements in your listening room. It is small due to the special structure of the utility model patent. Just place it where stationary waves are easy to accumulate, such as the corner of the room, near a speaker, and the back of your audio rack, to eliminate the stationary wave, and realize high sound quality full of transparency and good sound staging.

Dramatically improve the resolution and phase characteristics of your audio playback! The RHR-1 not only eliminates stationary waves, but also eliminates unnecessary reflections and band bias in the listening room, as a result, the playback sound and phase characteristics of the audio are dramatically improved.
In addition, the peak of the frequency characteristics equals the dip, so the timbre and texture of instruments and voice are dramatically improved. It results in three-dimensionality and clear sound image localization that cannot be realized even with the upgrade of amplifiers and speakers, and the vast sound field reproduction is realized with a fresh and smooth timbre and texture.

Below you see some installation examples. Please point the shallowest hole towards the listener.

Review:
Acoustic Revive RHR-21 Acoustic Resolution Exciters! Part 1 by Jef Day at posi+ive feedback
“I did notice that there was better resolution, more body to the images, an expanded soundstage, a more vivid sense of spaciousness at the recording venue, and a more natural “Real Sound” of the instruments.“
